Portable Electronics KEY SPECIFICATIONS THD+N at 1kHz, 105mW Continuous Average
Output Power into 16Ω 0.1 % (typ)
THD+N at 1kHz, 70mW Continuous Average
Power into 32Ω 0.1 % (typ)
Shutdown Current 0.3 ОјA (typ) Boomer audio power amplifiers were designed
specifically to provide high quality output power with a
minimal amount of external components. Since the
LM4811 does not require bootstrap capacitors or
snubber networks, it is optimally suited for low-power …
